I visited my brother, his wife and then infant daughter with our parents for Christmas some time in the early 2000’s. He had a small flat so it was packed.
We decided of all the Christmas things to do, we’d watch the exorcism of Emily Rose before we all turned in for bed, and because the flat was so packed I had to sleep on the sofa by myself.
No big deal I thought, until after everyone had turned into their respective rooms one of my nieces toys at the bottom of one of her toy bins started singing, completely unprompted and untouched. It finished its song then started making a child laughing noise before starting singing again.
I hid underneath the blanket and cowered praying that whatever caused it to start randomly making noise would go away. It continued on for what seemed like an age before it finally stopped. When I asked my brother and his wife if anything similar had ever happened the next day, they said any toys in the bins are always turned off before being put away so I’m assuming I either fell asleep and dreamt it or it was an extremely unfortunate coincidence, but it was the closest I’ve ever come to fearing the idea of ghosts etc.
Damn, at a glance I would not be able to tell some of these are from a game.
